This article presents a second-order derivative-based audio steganalysis. First, Mel-cepstrum coefficients and Markov transi-tion features from the second-order derivative of the audio signal are extracted; a support vector machine is then applied to the features for discovering the existence of hidden data in digital audio streams.

Results demonstrate that, in comparison with a recently proposed signal stream-based Mel-cepstrum method, the second-order derivative-based audio steganalysis method gains a considerable advantage under all categories of signal complexity--especially for audio streams with high signal complexity, which are generally the most challenging for steganalysis-and …

To improve Mel-cepstrum-based audio steganalysis, we formulate the second-order derivative-based MFCCs and FMFCCs, obtained by replacing the signal f in (12) and (13) with the second-order ¢ Q. Liu et al. derivative D2 ( ¢), the calculation is given by f d mel1 d mel2 Derivative MelCepstrum = FT (MT (FT (D2 ))) = f ... d melM (14) and df mel1 df mel2 Derivative …

To improve a recently developed mel-cepstrum audio steganalysis method, we present in this paper a method based on Fourier spectrum statistics and mel-cepstrum coefficients, derived from the second-order derivative of the audio signal. Specifically, the statistics of the high-frequency spectrum and the mel-cepstrum coefficients of the second …

Previous studies have shown that taking the second-order derivative of audio signal improves the performance of audio steganalysis [ 11, 12, 19 ]. Therefore, in the proposed method, the second-order derivative of signals is used for feature extraction.

For WAV format files, Liu et al. proposed a derivative-based Fourier spectrum and Mel-cepstrum audio steganalysis method , their experiments received a good performance when the hidden ratio is high. Later, Liu et al. used Mel-cepstrum coefficients and Markov transition features from the second-order derivative of the audio signal [ 12 ] and obtained a better …
